Role Can Hardware Design Play in Cybersecurity?
Keynote What
Srinivas Devadas - Massachusetts Institute of Technology
Room: Almaden Ballroom
Nary a day goes by without hearing about break-ins into software systems, with personal or confidential data being
compromised. Yet, as time goes on, we are trusting the cloud more and more to perform sensitive operations for us. emanding
more trust in software systems appears to be a recipe for disaster.
Can hardware rescue us? Suppose we only trust hardware manufacturers and cryptographers, and not system software
developers, application programmers, or other software vendors. It will be the hardware manufacturer’s job to produce a piece
of hardware that provides some security properties. The additional physical security that comes with hardware is a bonus;
however, there is still a leap of faith! We must trust that the hardware’s security guarantees really do take software out of
the loop.
This poses a challenging problem. Software that operates on our data is assumed to be curious or malicious. To make
matters worse, the cloud service provider can also be malicious and can run whatever program it wants on our data. How
can we ensure privacy of data despite the practically infinite number of malicious programs out there? In this talk, processor
architectures being developed in academia and industry will be described that are attempting to address cybersecurity and
privacy challenges through innovative hardware design.
Biography: Srinivas Devadas is the Webster Professor of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology
(MIT). He received his MS and PhD from the Univ. of California, Berkeley in 1986 and 1988, respectively. He joined MIT in 1988 and served as Associate
Head of the Department of Electrical Engineering and Computer Science, with responsibility for Computer Science, from 2005 to 2011. Devadas’s
research interests span Computer-Aided Design (CAD), computer security and computer architecture. In CAD, his work on logic synthesis and power
estimation resulted in several best paper awards at the Design Automation Conference and in IEEE Transactions. Devadas was elected a Fellow of the
IEEE in 1999 for contributions to design automation. He received the IEEE Computer Society Technical Achievement Award in 2014 for inventing Physical
Unclonable Functions and single-chip secure processor architectures. Devadas’s work on hardware information flow tracking published in the 2004
ASPLOS received the ASPLOS Most Influential Paper Award in 2014.

This session presents innovations in approximate and stochastic circuits. Approximate circuits allow precision to be trade-off for improvements in area,
delay and power. Stochastic circuits use random bitstreams to encode values
-- the value encoded is the probability any given bit of the stream is 1. The first
paper describes multi-level logic synthesis techniques for approximate circuits that
handle user-provided constraints on error magnitudes and frequency. The second
paper describes models for the error characteristics of approximate adders and
presents a new approximate adder design. The last paper offers an approach to
reduce the silicon area required to generate multiple stochastic bitstreams having
different probabilities.
Thermal management is critical to virtually all chips and electronic systems, from
mobile devices to supercomputers. The papers in this session present various
technologies for thermal modeling and management. The first paper proposes
a modeling framework for an integrated microfludic cooling and power delivery
system. The second paper deals with thermoelectric cooling and integrates a thermal
simulator with thermoelectric device models. The third paper improves the accuracy
of thermal measurements of integrated circuits by modeling thermal emissivity.

Embedded Tutorial: Automated and
Quality-Driven Requirement Engineering
Room: Almaden 1
Moderator:
Robert Wille - Univ. of Bremen
Organizer:
Robert Wille - Univ. of Bremen
The design flow for complex safety critical systems starts way before the
implementation phase. A considerate amount of time is spent on extracting and
organizing requirements from several documents that are provided by the stakeholders
and customers. This process is called requirement engineering and usually carried
out manually thus far. Some software tools, in particular IBM Rational DOORS1, are
available that mainly focus on providing methods to organize requirements and link
them to artifacts of the design flow. Besides extracting and organizing requirements,
designers also link them to model elements, code blocks, and verification plans such
they can be traced during the implementation phase. In this tutorial, we present
(automatic) methods which ease this flow, i.e. (i) analysis schemes checking whether
requirements are indeed formulated according to proper guidelines, (ii) automatic
approaches for the extraction of requirements from customer specifications, and (iii)
verification methods that check the extracted requirements for consistency. Natural
language processing tools and formal methods are used for this purpose.

Static timing analysis is a key component of any integrated circuit (IC) chip designclosure flow, and is employed (i) to obtain bounds on the fastest (early) and slowest
(late) signal transition times for various timing tests and paths and (ii) drive various
physical synthesis and physical design optimizations. Growing chip design sizes
and complexities (e.g., increased number of clock domains, increased significance
of crosstalk coupling, voltage islands), as well as more complex and accurate timing
models (e.g., current source models) lead to longer timing analysis run-times, thereby
hindering designer productivity.
Trade-offs are naturally performed on timing model complexity to achieve practical
turnaround-times for chip static timing analysis. To margin against the ignored (or tradedoff or uncertain) modeling limitations that are not explicitly and accurately modeled in
the native timing models, early and late signal propagation delays (for both gates and
wires) are made further pessimistic by the addition of extra guard bands. While these
forced early-late splits provide the desired safety margins, applying the splits for the
full path of some timing test introduces excessive and undesired pessimism if the data
path shares an overlap with the clock path. Common path pessimism removal (CPPR)
attempts to remove this pessimism by tracing these potentially problematic paths and
discarding some of the early-late difference along the common sub-path. This session
will showcase the techniques and methods used by the top-performing contestants of
the TAU 2014 Timing Contest to perform CPPR.

Moderator:
Jose Ayala - Complutense Univ. of Madrid
This session tackles the problem of managing the parallel execution and the data
integrity issues in embedded systems by means of novel software techniques. The
first paper proposes a context-switch-enabled pipelining approach for the synthesis
of data-parallel kernels. It formulates a scheduling problem for minimizing the
context-switching cost of the multithreaded pipeline with an exact formulation and
an efficient heuristic to solve the optimization problem. The second paper extends
previously proposed analytical modeling techniques in the field of floating-point
to fixed-point conversion to a larger class of programs. This approach extracts
a compact, graph-based representation of the program. Finally, it is presented a
warranty-aware page management design to mitigate the operation overhead
required for managing the endurance issue in PCM-based embedded systems.
